Dead motherboard

Because of the temperatures here in Sweden is so hot right now, I motherboard died when I was playing Left 4 Dead.
Because I have no money right now, so I can't buy me a new one for at least 1-2 months :(
So I won't be so active at the forum and I can't do any typesetting right now.

Thats really bad.
It seems we always lack of something, first a translator, now our editor... :(


Maybe your motherboard is still under warranty? You should have two years or more. You could try to get your money back...
I mean... overheating, in SWEDEN. Lol? Thats like a frozen computer in the Sahara^^ Maybe the motherboard-company is accomodating because of this.

You will laugh, it's real.

[A little boast]

I couldn't keep myself from boasting that, sorry. :mrgreen: :mrgreen: :mrgreen:

I've had the same problem here in Russia about four years ago, although I was overclocking my pc heavily. I've even made a liquid cooling system (yes, it was completely hand-made, nothing from the shop) which cooled cpu, north bridge and gpu, but then... condensers on the motherboard began exploding and leaking.
However, I've had enough soldering skill to fix it by installing new ones. That happened 6 times in a row. After all this I've reached stable working 4.2ghz out of 2.4ghz Northwood processor. Condenser exploding frequency was 4.6ghz.

Furthemore, I've voltmodded my video card and overclocked it to it's limit, but then I've had burnt away gddr memory chips on it. I've soldered it back, cleaned, put new "warranty void" seals, and returned it to the shop, because it was under guarantee.
It's a miracle, but I've got a new video card without any questions (even my name wasn't required, only a bill which proves that I've bought it in that shop). Then I've repeated everything with it... it is working even nowadays. :mrgreen: :mrgreen: :mrgreen:

It's around 30 degrees in Sweden right now! I love the global warming! :D

I found out that my motherboard(gigabyte p35 ds3) has 3 years warranty and my Power Supply Unit(corsair) has 5 years warranty.

Int 29Ah: you know much about computers, right? When the CPU is dead, the computer will start but give away some sound and you can see stuff on the screen?

But right now, when I press the start button. Nothing happens. The problem must be the motherboard or the PSU, right?

There isn't much time, I have to go now.

Some first thoughts:
1) When cpu is dead there should be diagnostic sound, but in most cases there isn't any. It depends on a motherboard.
2) Take PSU into account also, it can cause this sort of problems (I've had it)

The only way is testing components one by another

2 crazyankan:

I'm back from the countryside.

Some more thoughts:

1) Are you sure that it's about temperatures? It can be an unstable voltage in your house electricity network (however, corsair PSU's are excellent indeed).
2) When you touch your computer case (try touching it with your elbow - fingers will feel nothing), does it feel like electricity?
In this case, you have a short connect from something to your case, it leads to a voltage shift in a PSU and it's death.
Also, is your motherboard fixed to the case on a feet like this to avoid it's back contact?

3) Have you tested your PSU? Testing is like this: you disconnect it from the case and everything (while off, of course xD), connect some small load to it (a few coolers, neon lamp, and so on) [[!!!DO NOT TURN IT ON WITHOUT LOAD!!!]], then you take a clipper (or some wire) and connect a GREEN wire with any of BLACK in your ATX plug. This should turn PSU on. If coolers (load) is working fine, PSU is ok. Turn it off by removing this connection (G to B).

If PSU works, you can measure it's voltages with a multimeter.
In the same ATX plug:
red wire should be 5V, yellow 12V, orange 3.3V, white -5V (minus five volts), and blue -12V (minus twelve).
If values deviate about 10-15%, PSU is having a voltage shift and is the problem.

4) Take a look at condensers at your motherboard. Did they change shape (became "fat") or leaked?

5) Do you have lots of dust in your case? If you do, clean it, because it:
a) makes small elements overheat
b) collects static electricity


6) If CPU is burned, only diagnostic sound can help you, nothing can even possibly be on the screen.


The only reasonable method of finding your problem is testing components one by another.
You should find someone with a similar system (your friend maybe), and test each your component with his computer. It's impossible to say anything exact another way.

PS.
I've had all these issues myself, so I know what I'm talking about. :mrgreen: :mrgreen: :mrgreen:
